Below is slightly editted test (I only removed #include "confdefs.h") 
from gcc-2.95 configure which tries to detect whether printf 
supports format %p. With 28 July CVS version of libc.a this test 
fails.

-----------------------------
#include <stdio.h>

main()
{
  char buf[64];
  char *p = buf, *q = NULL;
  sprintf(buf, "%p", p);
  sscanf(buf, "%p", &q);
  exit (p != q);
}

-----------------------------
main () at xxx.c:6
6         char *p = buf, *q = NULL;
(gdb) n
7         sprintf(buf, "%p", p);
(gdb) n
8         sscanf(buf, "%p", &q);
(gdb) n
9         exit (p != q);
(gdb) p p
$1 = 0x908c4 "908c4"
(gdb) p q
$2 = 0x38c ""
(gdb) q
